500 OOPS: vsftpd: refusing to run with writable root inside chroot()

I have taken out write permission for usr/share/empty and I have also verified it by ls -l command but did not work. I have even put in allow_writeable_chroot=YES configure but nothing worked. Please Help me!

Hint: This issue is possibly caused by 2 boolean options:
These options can allow local login of users and write files.

Thanks for your answer but I have already overcome the issue. I was not able to take out write permission from the empty directory.
